STUDY OBJECTIVE To evaluate the cost effectiveness of the Nd-YAG laser and bronchoscopic electrocautery for palliation in patients with symptomatic tumor obstruction. DESIGN A retrospective study. SETTING Bronchoscopy unit of a university hospital. PATIENTS AND INTERVENTION Thirty-one consecutive patients with inoperable non-small cell lung cancer and symptomatic intraluminal tumor underw...

conclusions our study showed that the triple therapy of nd: yag and nd: yag + co2 fractional and hydroquinone cream had high efficiency and low morbidity compared to twofold treatment with nd: yag and nd: yag + co2 fractional. results seventeen patients with melasma (14 females and three males) with mean (± sd) age of 38.47 (± 6.29) years (range 29 - 53) were included in this study. the only si...

The Nd-YAG laser has good tissue penetration and coagulation effects thus has become an important weapon for photoresection of tracheobronchial obstructive lesions since 1980.Treatment of benign lesions including benign tumors and scar tissues using the Nd-YAG laser has good results. In the treatment of malignant tumors however, it has a lower effectivity rate when compared to benign lesions. F...

abstract today, the laser is used in a wide range of dental procedures. some of the advantages of some lasers in treatment of oral soft tissue lesions are: elimination of need for local anesthesia, minimal bleeding, fast healing, absence of postoperative complications and reduction of recurrence rate. for these reasons is was used for treatment of oral fibroma. to our knowledge this is the firs...

introduction: the aim of this study was to evaluate and compare the scanning electron microscope (sem) of indirect composite conditioned by erbium-doped yttrium aluminum garnet (er:yag) laser, neodymium-doped yttrium aluminium garnet (nd:yag) laserand carbon dioxide (co2) laser. methods: 18 indirect composite blocks (gc gradia da2, japan) with 15 × 10 × 10 mm dimensions were made. the bonding s...

Photodynamic therapy (PDT) utilizing Photofrin is proving to be effective for the treatment of early stage lung cancers. The effect of PDT utilizing YAG-OPO laser as new light source was evaluated in 26 patients (29 lesions) with early stage lung cancers. YAG-OPO laser is solid state tunable laser which is easy to change wavelength between 620 and 670 nm exciting various kinds of photosensitize...

The emission characteristics of debris from laser-produced tin plasma were investigated for an extreme ultraviolet lithography (EUV) light source. The ions and droplets emitted from tin plasma produced by a CO2 laser or an Nd: YAG laser were detected with Faraday cups and quartz crystal micro-balance (QCM) detectors, respectively. A higher ion kinetic energy and a lower droplet emission were ob...

Purpose: Comparison of astigmatic correction and visual acuity outcomes in patients implanted with toric intraocular lenses following cataract surgery reference marked pre-operatively manually with a pen or with YAG laser, in conjunction with the Sunalp YAG Laser Lens. Methods: 16 eyes from 16 patients were divided into two groups of 8 patients each. Pre-operativelly, the eye of one group was r...
